> It would be useful to have a flag that made {{hadoop fs -ls}} only print filenames, instead
of full {{stat}} info. The "{{-C}}" flag from GNU {{ls}} is the closest analog to this behavior
that I've found, so I propose that as the flag.
> Per [this stackoverflow answer|http://stackoverflow.com/a/21574829], I've reluctantly
added a {{hadoop-ls-C}} wrapper that expands to {{hadoop fs -ls "$@" | sed 1d | perl -wlne'print
+(split " ",$_,8)\[7\]'}} to a few projects I've worked on, and it would obviously be nice
to have hadoop save me (and others) from such hackery.
